Ironically, the issue we've been trying to resolve with CM9 for this phone, the rotation bug, appears to be fixed here. Not sure whether to laugh or cry :P

I've started to port the Galaxy Nexus image instead. The new version is a lot more stable, and I guess I've had a bit of a change of heart with regards to updating. This version is more complete and comes with all of the updated gapps, which means we get all of the awesome stuff that was shown at IO.
Remember to flash the boot.img in the zip.
When you're going through the setup, the waiting page (After you select language) takes a while, sometimes it fails and resets to the start of setup.
